SOL'DERlNG-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 602,368, dated April 12,1898.

Application filed June 1, 1897. Serial No- B39,018. (No model.)

To all whom it may concern:

Be it known that I, BERTRAND H. SHORT, a citizen of the Dominion ofCanada, residing at Vancouver, in the Province of British lumbia,Canada, haveinvented a new and useful Soldering-Machine, of which thefollowing is a specification.

My invention relates to machines for fluxing or soldering cans; and itsobject is to provide such an apparatus that will conveniently solderfiat oval cans of almost any form so long as the peripheries of the sameare of roundish form and to do the work with rapidity and despatch. Iattain this object by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 shows an elevation of my machine, whichillustrates its general arrangement when in use. Fig. 2 shows a planview in detail of one of the adjustable support-frames in which thecan-conveying mechanism is mounted. Fig. 3 shows a vertical intersectionof the machine, taken at line Ct at of Fig. 1. Fig. 4 shows one of thecan receptacles or sockets with its relative parts. Fig. 5 is aninverted plan View of one of the said cansockets; and Fig. 6 is anintersection of the same, taken through its center.

In the drawings similar numerals designate corresponding partsthroughout the several views. p

10 indicates sprocket-wheels mounted on shafts 11, which are suitablyarranged in forked bearings 12,'as shown in Fig. 2. One of thesebearings 12 is adj ustably mounted on a suitable frame 13, whose centerportion proj ects and fits between the vertical sides of the standard 15and is kept in place by the plate 14, which is secured on the projectingside of the same, and the projecting shoulders of the plate rest againstthe vertical outer sides of the standard. By reason of the bolts 12passing through slots in the projecting ends of the frame 13 and thewheel screw 17 taking through a lateral projecting portion of the frame12, as 12 it will be seen that the sprocket-wheels may be adjusted andset at various distances apart, and by the wheelscrew 16 the said wheelsmay be set at the desired elevations. It being necessary to use but theone wheel-screw 17 for setting the said wheels 10 apart, this isdispensed with on the other standard 15, (see Fig. 1,) and the frame 13is dispensed with also, but the projection which lies between thevertical sides of the said standard 15 being a lateral extending portionof the frame 11, which is similar at itsbifurcations to the frame 12.

'18 indicates a sprocket-belt taking round the wheels 10. This belt 18is provided at regular intervals with inverted shackle-links 19, havingperforations therein placed at an angle of about twenty degreesto theplane of the chain or belt. Suitably arranged in the perforations arespindles 20, which are retained in their proper position by collars 20,and on'the ends describing the greater radius are fixed can-receivingsockets 21, and, as better shown in Figs. 4, 5, and 6, these sockets aresecured to spider-castings 21* by screws or bolts 21, and they areself-adjusting by reason of the spindle 2O loosely passing through aslot 21 therein, and by reason of a collar 20, secured to the spindle 20and lying in close proximity to the said casting 21 and a flange 20,secured to the flat end of the spindle by a screw 20, it will be seenthat the can sockets or receptacles are selfadjusting and that as thecans are conveyed along a common runway at the angle above mentionedtheir lower edges will find a common radii by the shank of the spindle20 oscillating in the slot 21, and therefore cans of various shapes maybe rolled along without undue vibration upon such runway, and by reasonof the pinions 22 near the opposite ends of these spindles engaging inthe rack 23 the cans in the sockets 21 will be rolled along at a uniformpace without fiuctuatory movement.

\ As better illustrated in Fig. 3, to prevent the pinions while engagingthe rack 23 from dropping below their proper line I provide a projectingflange adjacent to the rack, as 23, and on the opposite side of the pathof the said pinion is arranged a guide-bar 24, which is supported inclose proximity to and above the axis of the pinions by extendingbrackets 24 suitably secured to the bed of the rack. This guide-bar 24effectuallyprevents the pinions from rising from the rack, and thusallow the cans to slide and escape the work.

As shown in Fig. 2, 25 indicates a hood for too the purpose ofpreventing the cans, which are placed by hand or otherwise into theinverted sockets 21 before entering this covering, from droppingtherefrom until the said sockets shall have passed beneath,and the lowersides of the cans will rest on and be supported by the beveled guide-bar26, (see Fig. 3,) when thelower. rims of the cans will be submerged inthe solder, which is in a trough 27, suitably arranged above a furnace.

In the operation of my machine sockets or can-receptacles are providedto receive the shaped cams that are to be fluxed, and these are securedto the spider-shaped castings 21. Motion is imparted to the machine by abelt taking round a pulley secured on the extending end of the shaft 11,(see Fig. 2,) and as the sprocket-belt carrying the can-conveyingdevices is passed in the direction of the arrow the cans (having firsttheir covers put on) are placed in the sockets 21 before entering thehood 25, and when the carriers reach the point where the rack engagesthe pinions the cans in the sockets 21 will be revolved in proportion tothe speed of the machine and after being first damped in acid will berolled through the hot solder, and consequently will be efiectuallysealed up, when at the opposite end of the machine they will be droppedfrom their holdings and be carried away by the belt taking round thepulley 29.

It is shown from the foregoing that my machine' is very simple and Veryeffective and will properly solder a large number of flat oval cans in ashort space of time, which is the object of my efforts.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. In combination with a machine for soldering cans of uneven radii,having a soldertrough arranged longitudinally above a furnace andbeneath a runway for cans, and sprocket beltwheels adj ustably arrangedabove and at either end of the said runway, shackle-links arranged atintervals upon a sprocket-belt taking round the said wheels, spindles 20arranged to loosely journal in apertures fixed at an angle in said links19, of self-adjusting can-receptacles 21 arranged on the depending endsof the spindles 20, and pinions 22 rigidly fixed near the opposite endsof the spindles and made to engage a fixed rack in their track,substantially as set forth.

2. In an apparatus for soldering cans of uneven radii, by means ofrolling movement over a receptacle of heated solder, the combination ofstandards 15 having adjustable frames arranged thereon, said framescarrying wheels 10 having a sprocket-belt passing therearound,shackle-links 19 inserted at regular intervals in said belt, the projecting portions of said links being turned laterally, of pinions orshafts passing through apertures therein, which apertures are at anglesof approximately twenty degrees to the plane of the sprocket-belt, ofcan-receiving sockets 21 adjustably arranged on the ends of the shaftsor spindles 20, of means for controlling said spindles from lateralmovement and means for imparting rotary motion to the same while passingover a solder-tr0ugh,whereby the canreceptacles will be rolled along acommon runway, as set forth.

3. In an apparatus for can-soldering, having wheels arranged at eitherside and a sprocket belt or chain passing over a common runway, spindlesarranged along'said chain, the same being provided with can-receptacleson their depending ends which receptacles are self-adjusting as toradius, pinions 22 rigidly fixed near the opposite ends of the saidspindles, a rack 23 engaging the pinions in their lower path, aguide-rod 24 made to engage the upper portions of the projecting ends ofthe spindles 20 in proximity to the pinions, while engaging the rack 23,substantially as set forth.

4. In a machine for soldering cans having sprocket belt-Wheels and abelt taking round the same, and can-conveyers arranged at intervalsalong said belt, the combination of spindles passing through aperturestherein, of can-receptacles adj ustably arranged on the ends thereof,and means for revolving the same at a uniform speed, as set forth.

5. In a machine for soldering cans, can-receptacles 21, spider-castings21 suitably secured thereto, the same having slots therein, spindles 20having flat shanks passing through the said slots and collars arrangedon either side of the said castings, and means for passing the saidcan-receptacles over a common runway by a rolling movement,substantially as and for the purposes set forth.

6. In a can-soldering machine having beltwheels arranged at either sideof a fixed trough, a frame adjustably arranged and made to support oneof the belt-wheels, a sprocket-belt having can-conveyers thereon andhaving a fixed angle to the line of the said wheels, a hood or guide 25secured to the branches of the frame 12, the same being made to engageand prevent cans from being detached from the conveyer while takinground the arc of the wheel 10, as and for the purposes hereinbefore setforth.

In testimony whereof I have hereunto affixed my signature in thepresence of two witnesses.
